isp residential germany cable

TITAN-NETWORKS is operated by Titan Networks Internet & Telecommunications Service Providing GmbH.

What it's used for

  • The address space carries residential and business internet services, evidenced by the reverse DNS record decix.gwxs.net.fra8.titan-networks.de which indicates a gateway for the Frankfurt region.
  • The AS announces 4096 IPv4 addresses across 1 prefix and 1 IPv6 prefix, while maintaining 95 observed neighbours. This ratio of a single /20 block against a high neighbour count suggests a regional access provider that aggregates traffic from multiple upstreams or peers rather than a large-scale transit carrier.

Notable

  • The registrant for the announced prefix 217.173.128.0/20 is Titan Networks Internet & Telecommunications Service Providing GmbH, which matches the registry holder exactly.
  • The address inventory consists of a single contiguous IPv4 block and a single IPv6 prefix, indicating a consolidated internal estate rather than fragmented leased space.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-14, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Reputation

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,771 prefixes, as published 2026-10-15. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
